![]() You’ll need a fancy scanner that can reprogram different systems in your car. This is the most common method that many mechanics and automotive professionals use to reset a crankshaft position sensor or a camshaft position sensor. How to reset camshaft position sensor with a scanner ![]() A scanner is essential in most cases, especially if you drive a Mercedes-Benz or any luxury car that has a lot of electronic control modules. If disconnecting the car battery doesn’t help, you’ll need to relearn the camshaft position sensor with a scanner. You can find it on a small placard stuck somewhere on your car like behind the door or in your owner’s manual. If you own a car with an anti-theft system, ensure that you have the anti-theft code before disconnecting the battery. The computer starts running things from square one so that they can work as well as they did before. When you’re turning it back on, it has no memory. The process clears the current state of the software, including any misbehaving codes. Think of it as switching off your computer or smartphone when it malfunctions. This also works well if you do not have an OBD-II scanner with you. If you recently replaced your camshaft position sensor but still got a code, doing this might help. The ECU will perform a relearn process that allows it to identify and connect to the new camshaft position sensor. Start with the positive terminal then the negative terminal. This helps to drain all the power flowing through the electricals. Get into the car and turn the headlights on. To make sure the process is full-proof, disconnect both the positive and negative battery cables and then connect both cables together. ![]() This helps to reset the engine control unit (ECU) and to clear any trouble codes stored for a faulty camshaft position sensor. Use a wrench to disconnect the negative battery cable and set it aside. This also works for resetting other engine problems and sensors, including the crankshaft position sensor. The easiest way to reset a camshaft position sensor is to first disconnect the car’s battery. It may also be necessary if you replaced other parts such as the timing chain or timing belt. You may need to reset a camshaft position sensor if you recently replaced it or if you did repairs to correct your vehicle’s ignition timing. This helps to match fuel delivery and ignition timing so that the engine can operate as it should. It measures the speed and position of the camshaft to make sure it’s in sync with the crankshaft. So unless he has some sort of proof that this is the issue, I would just ask if he is going to charge you to check the belt if that does not fix it.The camshaft position sensor is an important part of your car. ![]() If he doesn't find anything then you will be right back where you are right now. If he as not done something like this then he is going to be doing a lot of work to tear this down just to look. If the belt is causing the issue, then the cam and crank sensor will not line up as they should. This is off of a Chrysler product so your pattern is going to look different but the idea is the same. With a lab scope he needs to look at the cam and crank patterns to see if they are lining up properly. The proper way to diagnose this being a timing belt before he tears it down to look at it, is to use a lab scope. Also, if he checked the signal he should know if he is getting a proper signal. ![]() Again, this is why I am doubting it is the belt because I didn't read anything like that happening. The only way it would be the cam and crank pulleys being misaligned is if the belt jumped a tooth, or it was not put back together correctly. If you look the first two are wiring issues, the next is a possible misalignment of the cam and crank pulleys, the last is the sensor. If you look at this first attachment it gives the possible causes. Is there any history to this? Does the engine start and run? Or did it run and then just stop one day? Maybe I am missing something that he knows. ![]()
